SAFETY PAPER.

This invention relates to safety paper having certain features of improvement which enhance the difficulties of successful alterations or forgeries. More particularly my invention has to do withsuch a safety paper which may be produced expeditiously by a single operation, and which impresses upon its opposite faces in perfect register a desired arrangement of figures, marks, or lettering.

An exemplitication of the present invention is illustrated in the accompanying drawing wherein- Figure 1 is a face view of a blank check prepared from safety paper containing the present improvements;

Fig. 2 is a view of the reverse side of the check which is shown in Fig. 1;

Fig. 3 is a fragmentary View of the face side of the same check, showing the condition of a portion thereof after treatment by an acid or chemical; and

Fig. 4C is a similar view showing the reverse side of the check.

In the production of the present safety paper, the white or untreated paper may be unwound and passed through a bath containing a dye which colors both faces thereof and also impregnates the fibres therebetween, the degree of impregnation depending upon how the paper stock is sized. From this bath the paper is passed between a pair of pressure rolls having, if desired, a brass covering whereon is a desired design. During its travel between the rolls the paper receives therefrom an impression of this design which takes the form of a deeper or lighter tone of the color of the dye used in the bath.

Referring now to the drawing, the application of the dye during movement of the paper through the bath will result in a ground or body color 6 being applied thereto. Impressions upon this ground color, resulting from travel of the paper between the pressure rolls, may take at least two different forms. First, is an origin mark 7 of any selected form and serving, if desired, to indicate the source or maker of the product. And second, is certain text matter or lettering 8 which may take the form of conventional words, lines, etc. According to the present invention, all such impressions are alike in tone and characteristics, and are produced in a single operation by the pressure rolls.

The impressions transferred from the pressure rolls are displayed upon both faces of the paper, although in reversed appearance upon one side. As a consequence every mark which is displayed on the face of the paper, is duplicated on the reverse side thereof, the two sets of marks being in exact register. To produce the present safety paper a single operation only is required. The several kinds of impressions, regardless of how placed or displayed, are homogeneous so as to be susceptible to attack from the same chemical agent. Should the safety paper be subjected to an acid treatment which alters any portion of its surface design, all impressions of every character appearing onthe surface of't he paper so treated will be affected similarly.

Referring to Figs. 3 and 4:, I have shown at the right hand ends thereof blank portions to indicate the appearance of the paper after treatment by a chemical or acid.- It will be noted that all the ground color, together with all impressions thereon on both sides of the paper, has been removed or affected. It may be of advantage in the present safety paper to locate the origin marks 7 in a definite relation with respect to the text or form matter 8. This is accomplished readily by having both.

kinds of impressions produced in the same operation by the action of the pressure rolls, as already pointed out. In this manner each instrument produced from the present safety paper will bear the makers mark in a particular location which will be always the same. and the character of this mark may be chosen with reference to the remaining impressions so as to harmonize therewith, if desired, It may further be noted that I am enabled by the invention herein described to produce a finished safety paper check or instrument of two tones made from a single dye, and to display" upon such paper various impressions all in one tone, differing from the ground or body color. The location of the origin marks and text matter is always the same with reference to each other, so that there need never be any overlapping of one with the other.

I claim 1. A safety paper impregnated with a 0010 dye and having a surface design and text matter in the form of words, etc., in register on opposite faces of the paper, consisting of compressed particles of the dye coloring, substantially as described.

2. A safety paper instrument impregnated with a color dye and having a surface withtext mater thereon in distinguishable tones of the same color consisting of compressed particles of the dye, substantially as described.

3. A safety paper instrument having impressions constituting text matter and origin marks prearranged to occupy separate loca tions upon a surface which is dye-colored, the impressions consisting of compressed particles of the same dye color, substantially as described.

4. The method of producing a safety paper instrument Which consists in applying to the paper a dye treatment by which it is colored distinctively on both sides, and in impressing upon the paper so treated a design and text matter which appears in the form of a second tone of the same dye color visible on both faces of the paper, substantially as described.

5. A safety paper having a coating of dye coloring having compressed portions to provide identification matter in said coating.

6. A safety paper having a coating of dye coloring, and bearing identification matter of a color tone differing from the color tone of the coating consisting solely of compressed particles of the dye.

7. A safety paper having a coating of dye coloring on both surfaces thereof having registering compressed portions to provide identification matter in said coating on both surfaces.

8. A safety paper having a coating of dye coloring on both surfaces, and bearing registering identification matter on both surfaces of a color tone differing from the color tone of the coating which matter consists solely of' compressed particles of the dye.

9. A safety paper impregnated With a dye and having portions thereof compressed to provide color contrasting identification mat,- ter composed solely of compressed particles of the dye in said paper.
